Package com.luciad.view.gxy.labeling.algorithm.discrete Description

Handles discrete placements labeling algorithms.

ALcdGXYDiscretePlacementsLabelingAlgorithm

The main class of this package is ALcdGXYDiscretePlacementsLabelingAlgorithm. This class provides an abstract implementation of ILcdGXYLabelingAlgorithm. Labeling algorithms can easily be created using this class by creating a label iterator, a label placement iterator and a label placement evaluator. This class also has the advantage of being easy to wrap.

Implementations

This package contains a few ALcdGXYDiscretePlacementsLabelingAlgorithm implementations:

• TLcdGXYLocationListLabelingAlgorithm : This labeling algorithm tries a fixed number of custom label locations.
• TLcdGXYOnPathLabelingAlgorithm : This labeling algorithm tries to place the labels on a path.
• TLcdGXYInPathLabelingAlgorithm : This labeling algorithm tries to place the labels inside a (polygonal) path.
• TLcdGXYLabelPainterLocationLabelingAlgorithm : This labeling algorithm tries a number of label locations and bounds that are retrieved from the layer's label painter.
• TLcdGXYDependantLabelsRemovalWrapper : This labeling algorithm wrapper defines a dependency which can be used to define if labels are omitted based on the omitting of other labels.
